MAGNETO OPTICAL CURRENT TRANSDUCER WITH IMPROVED OUTAGE PERFORMANCE |
摘要 |
A MOCT metering system includes a cutoff module that ensures zero output when values from an optical module fall below a threshold value. The cutoff module includes an RMS to DC converter that drives a comparator. The comparator drives a switch that causes the cutoff module to pass through the measured signal unmodified if above a threshold value and to output a zero voltage signal if below a threshold value. |
